I recently purchased a 1998 MF 240S with less than 400 hours. I noticed the tach was working properly when I test drove it but foolishly didn't take the time to carefully inspect the rest of the gauges. The prior owner verbally confirmed they worked.
The oil pressure idiot light, fuel level and water temp gauges do not work. I don't know if it has a horn but does not work if there is one. Everything else works fine, including all of the lights and road flashers.
The manual references a single fuse block with six circuits. Interestingly enough, one of the fuses supports the "engine oil pressure warning light, fuel gauge, fuel tank sender unit, engine temperature gauge and brake lights". However, none of the six fuses were blown and I have continuity at each of the six fuses. Although not documented in the manual, I discovered two in-line 8A fuses wired into the large light switch. One is a yellow wire with good fuse and continuity. The other is a white wire that does NOT have continuity regardless of the position of the light switch. It appeared the original glass fuse was blown and I replaced it-- but still "no go" with the oil pressure idiot light, fuel and temp gauge.
I'm completely stumped. Any ideas / suggestions would be greatly appreciated! Thanks in advance.
